The Outdoor Rock Speaker OSD Audio RS850 is OSD's flagship rock speaker which is an excellent addition to your garden, poolside area or anywhere else in your landscape. With 200 watts of power that produces clear, rich sound over a 120 to 200-foot distribution area, this all-weather speaker is durable, reliable and designed to blend right in to its surroundings. It comes in sandstone canyon brown, granite gray or slate gray.

Do I need special cable to run outdoor speakers?
We strongly recommend our direct burial, CL3/FT4 waterproof cable and wire connectors that are designed for the outdoors. Our speaker wire uses a specially formulated UV-resistant, white polyethylene jacket that provides protection against water damage and allows the cables to withstand extreme weather conditions like rain, snow and high temperatures and incorporate twice the insulation of average cable. If you plan to bury the cable, OSD recommends you bury it 4-6" underground so that it's not visible nor pose a danger of somebody tripping over it. Our speaker cable is ideal to use in direct burial applications. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. 

Add Volume Controls
Volume controls can be a great addition to a system providing both proper impedance matching and more hands-on local control of the volume in the listening area. We offer a great selection of outdoor volume controls to choose from!

Extremely Durable
OSD outdoor speakers are developed with harsh conditions of the outdoors in mind. Our rock speakers use only non-water-absorbing materials and won't absorb any water. This is critical in winter so it won't freeze and crack. The shape is designed to withstand large amounts of pressure, extreme temperatures and moisture. Remember though, outdoor speakers are an investment, so take care of them. Storing them away from extreme weather conditions will only lengthen the time you will get enjoying outdoor speakers. These rock speakers utilize weather-resistant components for years of trouble free performance.

What's on your mind?

Linda Estill • 12/17/2019, 2:17:43 PM We are not tech savvy people. Does the speaker just need to be plugged into an AC outlet? Can I connect via Bluetooth to my android and Kindle?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Linda:The RS850 are our top of the line rock speakers, but it is a passive design that needs a powered (or amplified) signal from an Amplifier or Reciever to play music. We do have another pair of 8.0" passive rock speakers as well, our model RX805, which also needs a powered signal. Thes speakers are the basis of a Bluetooth Rock speaker kit featuring these same speakers; a model BTR-805 (Bluetooth Rock). It features a Master 8.0" Speaker that needs to plug into an AC outlet. Which delivers power to both an internal Bluetooth Receiver and a two-channel stereo amplifier. One channel connects to the inner 8" coaxial (2-way speaker). There is a speaker wire that runs from the Master Speaker to the matching Satellite Speaker (same as a single RX805 rock speaker) carrying the second stereo channel. So your Bluetooth enabled devices (Smartphone or Tablet) connects wirelessly to the Master Speaker's Bluetooth Receiver. The Master and Satellite Speakers should be placed between 8 to 12 feet apart for the best stereo separation.I hope that is not too confusing,
